B10THx20/1P-SC-S 2x1"INT HEX+2x3/4"INT HEX

B10THx20/1P-SC-S 2x1"INT HEX+2x3/4"INT HEX designates a SWEP B10T brazed plate heat exchanger with 20 plates in the pack. The H plate is the obtuse chevron: it gives the most heat transfer per plate and the most pressure drop, so it suits duties where approach temperature matters more than pump head. Reading the string: /1P is single pass; -SC is 316/316L stainless steel plates joined with copper. The closing S is the pressure class: 31 bar at 155 C. The connection field reads 2x1"INT HEX+2x3/4"INT HEX. The B10T plate pack measures 289 x 119 mm (11.38 x 4.69 in) on 243 x 72 mm port centres, and by SWEP's published weight formula a 20-plate unit comes to about 3.1 kg (6.8 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. Depth is the one dimension that changes accross the plate counts of a series, so measure the space behind the unit before moving to a larger pack.
